SOLE MACHINE.

Application filed March. 22, 1926. Serial No. 96,563.

' This invention relates to sole machines and more particularly to such machines employed in the manufacture of lipped insoles for shoes. As herein illustrated, the invention is embodied in a machine which, by a simple interchange of parts, is adapted for use both in pressing together the flaps of a channeled insole to form a stitch-receiving lip 0r rib and also for applying reinforcing fabric to one face and against the lip of a lipped insole. Usually an adhesive will be applied to the appropriate portions of the insole or fabric before they are presented to the machine for either of said operations. As already suggested, the machine when fitted for either of thesetwo operations may be changed over to adapt it for performing the other operation in a simple manner andin a relatively short time.

The object of the present invention is to improve the construction and mode of operation and to facilitate the adjustment of machines of the general type above described, to increase the durability of such machines and to reduce the time and attention required for maintaining them in successful and eflicient operation.

Accordingly, for the accomplishment of that and other objects, the present invention comprises certain novel combinations and arrangements of parts which will nowbe describedin detail in connection with theacco'mpanying drawings which illustratethe preferred embodiment of the invention with the parts needed for performing both operations above referred to and the invention will then be particularly pointed out in the appended claims.

In the drawings:

Figs. 7 and 8 show respectively in side and nd elevation a special form of the feed or 00 canvas roll;

Fig. 9 is an end elevation of the machine as fitted for the lip pressing operation, and

Fig. 10 is a sectional elevation, similar to Fig. 6, also showing the machine as fitted for lip pressing.

Referring particularly to Figs. 1 to 6, the work engaging tools include a pair of feed rolls 20, 22 and a work positioning or pressure roll 24 which functions also as a feed roll. These rolls may have the shapes and relative arrangement which are clearly shown in Fig. 6. The roll 20 is shaped to engage the reinforcing fabric'or canvas R and press it progressively, lengthwise of the lip, into the angle formed between the body of the insole S and the lip formed by uniting the two flaps L, L, as will be further explained in connection with Figs. 9 and 10. The lower feed roll 22 is shaped to engage the outer side of the lip L, L and also the feather F ofthe insole while the pressure roll 24 has the general shape of a double truncated cone and the bulging portion of this roll engages the unlipped surface of the 35 insole at a point substantially opposite the lip and substantially opposite the space betweenthe rolls 20, 22. Under usual conditions, these three rolls are positively driven to rotate at substantially the same peripheral speed but the relative speed'and the shapes of the rolls may be modified to suit diiferent kinds of work and different working conditions, as will be further explained. The upper'feed roll 20 is formed on the end of a removable section of a horizontal shaft 26- rotatable but fixed longitudinally in bearings in a carrier 28 which has a limited rocking movement upon a shaft 30 which is located heightwise between the axes of rolls 20 and 22 and is rotatable inbearings of brackets 31 extending inwardly from a removable housing 32 forming the front sec-'- tion of the head of the machine. With this construction, the roll 20 in its movement toward and from the roll 22 travels approxithe rolls.

In order to provide for ready adjustment longitudinally and complete removal of the roll 20 and its section of the shaft, the latter is slotted, as indicated at 33 in Fig. 2, and a screw 34 passes therethrough and through a split spring collar 35 ,(see also Fig. 5) loosely surrounding the shaft and threaded to receive the lower end of the screw. By tightening the screw the collar may be clamped to the shaft, thus firmly holding it and its roll in the longitudinal position to which they have been adjusted by the operator. A joint 36 permits a slight. relative movement between the two sections of the shaft 26 while maintaining their driving connection.

As shown in Fig. 3 the carrier 28 is provided with an extension 37 normally pressed against an adjustable stop 38 by a spring 40 the force of which may be adjusted bya screw 42. The housing 32 and also the corresponding housing at the rear of the machine, to be described, are constructed and mounted for ready removal from the machine so that the various parts may conveniently be inspected, adjusted or exchanged. To that end the housing 32 is provided near its lower end with holes which have a sliding fit over studs 44 to which the housing may be clamped in its proper position by set screws one of which is shown at 46.

The feed roll shaft 26 has secured to its rear end, as shown in Fig. 5, a pinion 50 driven through an intermediate gear 52 by a gear 54 secured to the shaft 30. Another gear 56 (Fig.

2) secured to the shaft 30 meshes with a gear 58 fast to the main shaft 60 of the machine. At the front end of this shaft 60 the feed roll 22 is secured'by a screw '62 threaded into the reduced end 64 of the shaft. As shown in Fig. 6, this reduced portion of the shaft has also secured to it a canvas clearing wheel 68 with peripheral teeth 70, this wheel being spaced, however, from the rear face of the feed roll 22 to permit the entrance of the canvas trimming knife, as will be later explained.

. The pressure roll 24 is securely held in adjusted position at the upper end of its vertical driving shaft 72 by expanding the hollow, split, upper end 74 of the shaft through the action of a screw 76 threaded into the hollow end of the shaft and having a conical portion 78. The shaft 72 is rotatable in a carrier 80 being driven by a bevel gear 82, secured tothe shaft, which meshes'with a gear 84 secured to a horizontal shaft 86 which in turn carries a gear 88 having relatively long teeth to mesh with a gear 90 secured to the shaft 60. The shaft 86 is carried by and longitudinally movable with a non-rotatable sleeve 92 forming a part of or rigidl-y secured to the carrier 80. To this sleeve may be clamped a block 93 from which extends laterally a steady pin 94 fitting a hole 96 in the frame of the machine. Thus, the carrier 80 and the parts carried thereby may be adjusted both angularly about the axis of the shaft 86 and also longitudinally with respect to the rolls 20, 22 and then securely held in adjusted position by tightening the clamping screw 98 and thus clamping the block 93 to the sleeve 92. Accordingly, the pressure roll 24 is compelled to move in a straight line, generally perpendicular to the axis of the pressure roll, in its imovementtoward and from the other rolls and, therefore, it occupies the same vertical relation to the roll 22 in all of its positions and when operating on soles of diflercnt thicknesses. Moreover, when the screw 98; is loosened and the block 93-unclamped from the sleeve 92, the carrier can be adjusted angularly to vary the lead of the roll 24, i. e. its relation along the line of feed with respect to the other rolls, as is sometimes desirable under specific operating conditions. The tightening of screw 98 will secure the roll 24 in such adjusted position. As illustrated in Figs. 1 and 4, the block 93 is provided with a slot 104 in which is slidable a block 106 carried by an arm of a lever 108 which is pivoted upon one of the rods 44 already referred to. A spring 110 is interposed between the head 112 of the machine and'a lug 114 projecting downwardly from the lever 108. An adjustable stop 116, passing through a forwardly extending bracket 118 of the head 112 in position to engage the lug 114, limits'the inward movement of carrier 80 and its roll 24 under the influence of spring 110. As shown in Figs. 1 and 3 the lever 108 has an arm 120 connected to a treadle (not shown) through a rod 122, lever 124, and treadle rod 126. By depressing the treadie rod the pressure roll 24 is moved in a straight line directly away from the feed rolls 20, 22. During this movement the car rier 28 and the feed roll 20 are lifted away from the lower feed roll 22 through connections including an adjustable screw 128 threaded into lever 108 and engaging a vertical rod 130 sliding in a hole in the head 112 of the machine'and engaging the lower side of the carrier 28. By adjusting screw 128 the precise timing of the movementsof the pressure roll 24 and the feed roll 20 with relation both to each other and to the lower feed roll 22 can be varied as desired .and especially when feed rolls ofdiiferent sizes are substituted as, for example when changing the parts as required to adapt the machine to operate on soles for mens rather than womens shoes. Normally the adjustment will be such that roll 20 will operatively engage the work slightly before roll 24 does in order to secure the best quality of work.

To facilitate placing the sole S initially with its lip L, L and the reinforcing fabric R in proper relation to the feed rolls and to maintain such relation throughout the operation of the machine thereon, several gages or guides are provided some or all of which may be utilized upon any particular kind of sole according to its special characteristics and otherv operating conditions. For example, different gages will often be employed for soles for meris', as compared with womens, shoes. As shown particularly in Fig. 4 there is provided in advance of the lower feed roll 22 a guide or guard 138 which is located to engage the sole in the vicinity of the outside angle of the lip. This guide is clamped in a block 140 having a cylindrical stem 142 which may be adjustably clamped in the head of the machine by a screw 144, the guide 138 being secured in adjusted position in the block 140 by a set screw 1 46. g

For the purpose of maintaining the sole at the desired angle, for example with relation to the end face of the tool-20, as shown in Fig. 6, there is provided a.sole guide .148

l which may be clamped in a block 150 by a set screw 152 (Fig. 4), the blockil50 being provided with a rearwardly extending stem 154 which may be adjusted angularly and longitudinally and then clamped in adjusted position in the head .112 by a set screw 156.

. Another guide 160, shown for example in Fig.

' roll.

5, is mounted to bear upon the unlipped surface of the sole just in advance of the pressure This guide may be clamped in a block 162 by a set screw 164 and has a depending stem 166 which may be adjusted in the carrier 80 and then clamped by a set screw 168. All three of these guides or gages are thus mounted for adjustment in three directions to meet varying operating conditions but it is to.

be understood that upon certain kinds of work, with different operators and under other operating conditions it may be unnecessary to make use of some of these adjustments and, indeed, in some cases equally good work can be done without using some of these guides at all and particularly. the guide 160. These guides also function to some extent as v guards to prevent the operators fingers or clothing from being drawn between the feed rolls.

As illu strated, the machine is provided with means for trimming the margin M of the canvas flush with the top of the lip L,-L or trimming both said margin and the lip, as shown in Fig. 6. The trimming means shown comprises a disc knife 17 4 which, as indicated in Fig. 2, is removably secured to the end of a horizontal shaft 176 which is engaged by spring actuated plunger 17 8 to cause the outer face of the knife 17 4 to be pressed firmly against the inner face of the feed roll 22. A movable guard 17 9 for the knife is fixed to a pin 172 (Fig. 4) which is slida'ble and rotatable in apart of a housing 193 and whichmay be clamped in desired position by a setscrew 173.v The knife shaft 17 6 rotates in a rock shaft toward and from the axis of the feed roll 22. The lever 180 may be clamped in adjusted position by manipulating a screw 184 which bears against a. slide 185 having a surface 186 complementary to a cylindrical surface of the fixed stud 181. By tightening the screw 184 the lever 180 will be clamped firmly to the stud 181 and the knife 174 will be maintained in the desired overlapping relation to the feed roll 22. The knife shaft 176 is rotated at highspeed by connections comprising gears 187, 188 and 189 (Fig. 3), the latter being mounted on a shaft 1.90 (Fig. 2) which is in line with the stud 181. Shaft 190 also carries a gear; 191 meshing with a gear 192 on a clutch member 232 to be described. Shaft 190 is mounted in bearings projecting from a housing 193 which is complementary to the housing 32 referred to aboveand which like the latter is readily removable from the machine, being supported upon rods, one of which is shown at 194, and clamped in adjusted position by screws such as 196.

Inasmuch as the layer of canvas R is united to the sole by an adhesive which is in sticky condition while the sole 'is passing through the machine, it is desirable to supply oil to the feed roll 20 and to the canvas clearing wheel 68 to prevent the canvas from adhering to the machine parts. This oil may be supplied from'a cup 198 to the roll 20 and to a felt pad 200 below the roll and in contact with the clearing wheel.

For conveniently sharpening the knife, a grinding wheel' 208 is so mounted that it may be readily moved from inoperative position shown in Fig. 4 into operative position where it engages the rear face of the knife 174, as shown in Fig. 3. The grinding wheel is mounted upon a shaft 210 which is freely rotatable in a bearing 212 carried by a bracket 214 having a handle 216, the bracket being pivoted upon a,sh'aft 218 rotatable in the housing 193. A spring 220 surrounding the shaft 218 tends constantly to turn the grinding attachment into its inoperative position shown in- Fig. 4. It will be noted that the axis of the grinding wheel 208 does not intersect the axis of the knife 174 and, because of the angular relation of these parts at the point or points of contact where the tangents to the circles of the wheel and knife are at an acute angle, the grinding wheel is caused to turn comparatively slowly'by reason of its engagement with theknife. As the grinding wheel is reduced in diameter by wear the bearing 212 and the wheel 208 may be adjusted ina direction perpendicular to the axis of shaft 210 by means of an adjusting screw 222 the head of which engages a slot in a longitudinally-movable non-circular rod 224 which carries the bearing 212. 226 indicates a sheet metal guard for the grinding Wheel.

For driving the main shaft 60 and the parts connected therewith, there is provided a clutch member 230 (Fig. 1) which is keyed to the shaft 60 and which may be shifted into frictional engagement with a co-operating clutch member 232, freely rotatable but not movable longitudinally, upon shaft 60. A gear 236 upon the clutch member 232 is driven through gears 238, 240, 242 and 244 from a vertical shaft 246 in the column 248 in the machine. Conveniently this shaft 246 may be driven by an electric motor in the base of the machine. The engagement of the two clutch members 230, 232 may be controlled in the usual manner through a spring and a treadle (not shown) which actuate a treadle rod 250, a lever 252 and a block 254 slidable with member 230 on shaft 60. It will be observed that gear 192 and knife 17 4 are driven continuously at a high, uniform speed even when, through relative slip permitted between, or disengagement of, clutch members 230, 232, the feed rolls are driven at slow speed or are at rest. From the practical standpoint, this arrangement is advantageous because the cutting action of the knife is then equally effective whatever the rate of feed of the work, for example at the toe of the sole where that feed may be slow.

Supports for the soles before and after they are operated upon by the machine are shown at 260 and262. A scraper 264 and a chute 266 conduct the trimmed material to a receptacle 268.

Under usual conditions a roll 20 witha circular end face does entirely satisfactory work but the form of roll 20 shown in Figs. 7 and 8 may be preferred because the acting edge 21 is polygonal with rounded corners and tends to force the canvas R more firmly into the angle of the lip; I

Figs. 9 and 10 illustrate the machine when equipped with substitute fittings adapting it, as above described, for; the operation of pressing together the two flaps L, L- preparatory to the application of .the reinforcing fabric. As is customary for this lip pressing operation, the surfaces of the flaps which are to be united are previously provided with an adhesive and are then consolidated into a unitary stitch receiving lip or rib as they are progressively turned up from the body of the insole and pressed to-' gether. For this purpose, instead of the housing 193 carrying the canvas trimming knife .174, there is mountedin the machine a similar housing 193' suitable for the lip setting operation which requires no trimming mechanism and consequently no grinding attachment. Moreover, preferably the the sole opposite the feed rolls shown in Fig. 6 are replaced by cylindrical feed rolls 20, 22 and 24 of the shapes and sizes indicated in Fig. 10. Furthermore, the guides 138 and 148 are replaced by plows 138' and 148 which are inserted beneath the flaps lying initially close to the body 'of the sole as shown at the top of Fig. '10 and which progressively raise them toward each other for the action of the feed rolls 20, 22 which press the li s together to form'a unitary lip, as alrea y described.

As shown in Fig. 9, not only is a guide 160, similar to guide 160, provided on the entrance side of the feed rolls but a corresponding guide 160 is provided on their exit side.

Fig. 9 also best'illustrates hollow bosses 261 which are integral with and extend in-' wardly from the housings 32,193 and 193 and the ends of whichbear against a central portion 263 of the machine frame and thus locate the housings in their proper position in the machine. The housings are further clamped in place by'bolts 265 threaded into said portion 263 of the frame and by a connecting link 267 pivoted to housing 32 and held by a set screw 269 in housing 193 or 193'. i
